Abstract: Objective: To evaluate continuous electroencephalography (CEEG) monitoring in assessing and predicting the prognosis of patients with critical cerebral hemorrhage.Methods: CEEG's classification was dynamically recorded at the bedside of 30 cases of critical cerebral hemorrhage with Glasgow coma scale ≤ 8.The outcome was evaluated cording to the Young criteria.All the patients were followed up for 2 months,and the correlation between the results of CEEG's monitoring and the prognosis of the patients was analyzed.Results: The CEEG of 30 patients with critical cerebral hemorrhage was nearly always markedly abnormal.The occurrence of nonconvulsive seizures was observed in 10% of the patients and convulsive seizures in 3.3%.The unfavorable prognosis rate in the cases with CEEG classification of Ⅰ and Ⅱ was 11.8%,while it was 53.8% in cases with CEEG classification of Ⅲ-Ⅵ.The difference was significant (P=0.019).Conclusions: The CEEG classification is markedly correlated with the prognosis of patients with acute critical cerebral hemorrhage,and CEEG monitoring might be of certain value in predicting the outcome.
